coming in and the ZAP device is not ringing:

-------------------

i am using the following setup:

ISDN (PTP) <-> AVM FRITZ CARD <-> ASTERISK <-> HFC CARD <-> ISDN phone

here is my zapata.conf:

---------------------
[channels]
switchtype = euroisdn
signalling = bri_net_ptmp
pridialplan = local
prilocaldialplan = local
echocancel = yes
overlapdial = no
immediate = no
usecallerid = yes
group = 1
context = isdn2out
usecallingpres=yes
musiconhold=default
channel => 1-2
threewaycalling=yes
transfer=yes

-----------------------

Someone please give me a hint i am already 2 days at this problem and i am
not able to solve it. 

Thanks
Jens
